SIGNALING DEVICE.

, Be it known that I, GEORGE lawnnncs, a cltlzen of the United States,'-rcs1ding at Melrose Park, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Signaling Devices, of which the followin is a specification.

My invention re ates to'signalin devices and more specifically to that class t ereof in which a pencil of ii ht is the medium employed in effecting t e signaling purpose.

The object of my invention is to provide a 1 device adapted for the production of a light pencil as stated, so designed as .to be ap plicableupourailway trains, automobiles, and other similar conveyancein which a danger or ,other signaling means may be found desirable.

A'further-object is the rovision of a device as stated by means 0 which the pencil of light ma be thrown in any direction and Man ang e. and whereby a comprehensive signa ing code.may be compiled.

A- further object is to provide'a mechanism as mentioned which may be readily and easily operated and which will be comparatively'slmple and economical of construction.

d Other objects will appear hereinafter.

With these objects in view my, invention consists in asignaling device characterized as above mentioned and in certain details of construction and arrangement of parts all as will be-hereinafter fully descrlbed' and more lparticularly pointed out in the ap pende claims.

M invention will be more readily understoo by reference to the accompanying drawings forming a part of this specification, and in whic F igure 1 is a side elevation of a portion of a locomotive boiler and cab equipped with the preferred form of my slgnalmg device, the cab being shown ill section, Fig. 2 is a top plan view thereof, showmf, the cab in section, Fig. 3 is a horizonta section taken on the linear-10 of Fig. 1, and Fig. 4

is a vertical transverse section taken on the line y+y of Fig. 1.

Referring now to the drawings, 1 indicates an ordinar locomotive boiler and 2 the locomotive ca Rigidl attached to the up or side of the former a jacent thefront en of the cab 2 is a metallic base 3 having a vertical socket or bearing 4, into-which is fitted for rotary movement, a shaft 5 the Specification of Letters Patent.

same being secured therein by a nut 6 I threaded upon the lower extremity thereof.

Extending outwardly and upwardly from" the upper end of the shaft 5 are diametrically opposed arms 7-7 in the outer end portions of which are formed axiall' alining bearings 8,8. Having its reduced e ings 8-8 is a sha- 10 formed inte' al with which is an arm 11 disposed at rig t angles to said shaft and into.the upper end of which is screwed an electric light socket 12] of any well known construction, the elecf trical connections with which ma be made throu h passages 13 formed .in t e arm 11 and t e shaft 5 for that purpose. An inf candescent li ht bulb 14 may be connected 1 7 Tea 12, the light emitted there;

with said soc from being reflected by means of a suitable reflector 15.

Secured to one of the endsi9j nd por-y tions 99 rockin 1y mounted in said bearof the shaft 10 is a beveled pinion 16 into 1 which meshes an annular gear 17 supported loosely upon a circular plate 18 which is secured as by bolts 19 to the arms 7--7, as

well as to arms 2020 formed integral with and projecting from the base socket 4 by bolts 21 passingthrough angular fittings 22-22 resting upon said plate, said fittings serring as bearings for said annular gear.

Lugs 23-23, shown in Fig. 4, projecting from the arms 7-7 and overlap in the up per surface of. said plate aid in liol ing said gear in place, the ends of the arms 2020 and said fittings 22-22 which bear against the inner edge of the ring or inner flange 24 of the gear 17, serving to center the latter.

Upon the 'periphe formed sproc ct tech 25 which are con nected, by means of a sprocket-chain 26 to a of the gear 17 are able bearing guide 33 formed upon and up- I wardly projecting from thebase 3, as clear shown in Figs. 3 and 4.- By means of a rod yor stem 34 formed preferably integrally with 'anduearwardly projecting from the rack 32 through a supporting bearing formed integrally with and laterally projecting from bracket 29, saidrack, and hence said gear 31Lv may evidently be operated. To facili: tate the actuation of Stud rod 34, the rearward extremity thereof is preferably provided with a handle or grip 36. "A hand screw 37 threaded into thebearin 35 adapted to contact the rod 34, is provi ed to effect 7 the locking of the latter in any position in saidbearing to which it may be adjusted.

@The operation of the device is as follows:- U'pon-- asping the handle 36 and moving the racli 32, the shaft is caused to rotate,

relative to t e line of movement of'the vev such rotation causing the shaft to be re volved in a horizontal plane, hence the latter may be ositioned in any desired angle hiele upon which .-the device is arranged. Assuming that when the rack 32 is in nor- .mal position the .axis of said shaftis at right angles to the path of the locomotive,

' it follows that. upon grasping the handle and rotating the gear 17 through the. medium of the sprocket-chain 26 and-s rocketthereby moving the signaling lam wheel 27,'th e shaft '10 maybe cause to rotate or to oscillate to any extent desired,

accord- -.ingly. This would cause the penci of light thrown from the lamp which is ordinarily directed toward the zenith, to move back and forth in' the train of the path of the loco- -"motive. 'Should thelshaft 5 be rotated, the movement of said light pencil desired may be. thrown at any des red angle to said path. It follows, therefore, that a pre-arranged code of signals may be utilized to enable 10- comotive engineers to determine therefrom the relative positions and direction of movement of locomotives on the same or other tracks, which could not be seen by them. For example, a vertical position of a light pencil might indicate the locomotive to be standing upon a side track. If held steadily to tbc right, that. it is standing upon the I right hand main track,vand if oscillated in a given direction, that it is moving in that T :2.direction, upon a given track. The simplictom would tend to obviate ii any series of acity, accuracy, and efi'ectivcjss of such a syscidents not otherwise 'avoi able.

While I have shown what I deem to be the preferable form of my device I do not wish to be limited thereto as there might be many changes made in the details of mnstruotion and the arrangement of parts without departing from the spirit of the invention com-.

prehended within the scope of the appended claims. And although I have designed my device with special reference to locomotives .I may Iuse the same inany other connection to which it is ap licable.

, Having described my invention what I claim asnew and desire to secure by- Letters Patent is: a

'1.'Th e combination with a railroad locomotive of a base member; a vertically rotatable member mounted in said base member;

a horizontally rotatable shaft mounted in said vertically rotatable member; a light and a reflector therefor mounted on said horizontally rotatable shaft, and adapted to project. a pencil of li ht upwardly; and

means in the cab of said locomotive for adjusting said member and shaft angularly,

substantially as described.

2. The combination with a railroad loco motive of a base member; a vertically rotatable member mounted insaid base member; a horizontally rotatable shaft mounted in said vertically rotatable member; a light and a reflector 'therefor mounted on said horizontally rotatable shaft andadapted to project a encil of light upwardly; a beveled gear 'xed to said horizontallyrotatable shaft; a beveled gear rotatably mounted on said vertically rota-table member and meshing with said first mentioned beveled gear; sprocket teeth on the peripher of the other bevel gear; a sprocket wheel ocated in the,
